Review of the Triodos Bank, Cash ISA:

Ethical banking

We feel very happy to bank with Triodos knowing that our money is going towards an ethical, environmentally friendly future. Reviewed on: 7th April 2023

Ethical Investment Yay! What's not to like

5
I save with Triodos and would like to bank with them as a current account too but do not have sufficient income to pay the fees but wholeheartedly support both the ethical stance and a nominal fee if this could be scaled according to means to allow more people access to their current accounting . A good bank in a horribly suffering world . Good customer service. Highly recommend them Reviewed on: 26th February 2021

Easy, straightforward and ethical.

5
If you have money to invest, it has to be an ethical ISA. It's a win-win for the ideas and communities that Triodos invest in and for the investors. Banking with Triodos is easy and straightforward and the interest rate is pretty good too. Reviewed on: 26th February 2021

The best way to invest your money 'greenly'

4
As someone looking to invest in a cash ISA but also wanting to avoid putting my money somewhere that might invest in areas I don't want to support (fossil fuels, arms, tobacco, etc.), Triodos was by some distance the best choice. I'm very happy to have done this. Reviewed on: 26th February 2021

It is possible to invest in a way that helps others. That's important.

5
I feel confident that not only is my money not doing harm, but that it is doing good. I don't have a lot of money, but what I do have, I want to make sure is being used as a force for good. I think that should be the minimum requirement for all investment, and hope for a future when that is the norm, and not unusual. In the meantime, Triodos is leading the way, and in a small way, it helps create a feeling of connection to others. Reviewed on: 26th February 2021
